Enabling DEP hardware level or Explicit PAE is preffered ? If enabled DEP on hardware , do we need to do any configuration on OS or application like sql server ? Can we enable or Disable DEP on hardware at anytime ? .In that case how OS and application behave What are the benefits of Enabling DEP on hardware level ? Thanks

Hi, DEP configuration is totally depends on the processors.The 64-bit processors made by AMD and Intel include hardware support for data execution prevention (DEP). Windows Server uses DEP to prevent malicious code from being able to execute, even when a buffer overrun occurs. Even without a processor that supports DEP, Windows Server can detect code that is running in memory locations where it should not be.

bcdedit /set [{ID}] pae ForceEnable What is {ID} in the above command

bcdedit /set [{ID}] pae ForceEnable What is {ID} in the above command [{ID}] The {ID} is the GUID that is associated with the boot entry. If you do not specify an {ID}, the command modifies the current operating system boot entry. If a boot entry is specified, the GUID associated with the boot entry must be enclosed in braces { }. To view the GUID identifiers for all of the active boot entries, use the bcdedit /enum command.
